The A.J. Antunes 8103116202 Low Gas Pressure Switch is essential for the safety of HVAC systems. It measures the pressure of the gas and when the pressure falls below 1/20” WC the switch turns off. This action can trip an alarm or stop the execution of further work on the equipment helping to avoid further mishap. It has a 1/4” NPT connection and a manual reset making it easy to install and service. This switch helps provide better performance, avoiding frequent breakdowns owing to low gas pressure problems, and creating safe working conditions. It is especially found in gas-fired heating cooling equipment such as furnaces and boilers.
